Type 2 Diabetes Mellitus: Pathophysiology, Clinical Manifestations, and Prevention Strategies
Overview
This paper examines Type 2 Diabetes Mellitus as an endocrine system disorder characterized by insulin resistance and progressive pancreatic dysfunction. It discusses the pathophysiology, clinical symptoms, serious complications including cardiovascular and renal disease, and emphasizes that up to 90% of cases are preventable through lifestyle modifications including physical activity, weight management, and balanced nutrition.

Module 3 Discussion: Type 2 Diabetes Mellitus
I chose Type 2 Diabetes Mellitus, a disorder of the endocrine system. Type 2 diabetes develops when the body becomes resistant to insulin and/or the pancreas gradually loses its ability to produce enough insulin. This causes glucose to build up in the bloodstream instead of entering cells for energy.
It manifests with symptoms such as increased thirst, frequent urination, fatigue, blurred vision, slow-healing cuts, and tingling in the hands or feet. Many people have no obvious symptoms for years until complications appear. In the body, chronically high blood sugar damages blood vessels and nerves, leading to serious complications including heart disease, stroke, kidney failure (nephropathy), vision loss (retinopathy), nerve damage (neuropathy), and poor wound healing that can result in amputations. It also increases risk of infections.
One interesting fact is that Type 2 diabetes is largely preventable. Up to 90% of cases could be avoided or delayed through regular physical activity, maintaining a healthy weight, and eating a balanced diet. It is the most common form of diabetes, affecting over 90% of the estimated 38 million Americans with diabetes.
